ACT Mobile Live is lacking resources or user needs to learn more?

I am a happy and satisfied user of ACT, and used ACT link with some smart phones in the past and worked great. But I think I did a mistake with ACT Mobile Live. Maybe I need some support to learn to use better, or the product is not good enough yet.

1.- I did not find the option to try 30 days free ACT Mobile Live, Now I am not happy with the product.

2.- I am Black Berry smart phone user. My model SP8350RIM is not included in the setup of ACT for Mobile Live.

3.-ACT Mobile Live do not have an option to SYNC with a GROUP of contacts. It only allows you to create a SYNC criteria using field names, but do not allow you to choose a GROUP of contacts already created in your contacts database. I would like receive some help if some can teach how to do it

I will appreciate some help to learn how to create a Sync criteria for a GROUP already created in the PC Contact database.

4.- I do not understand how any smart phone can handle easily over 2500 contacts and it is hard for ACT Mobile to do it. Maybe I am a user ignoring technical limitations and only I see from a user point of view that want to use it without limitations.

5.-The blackberry that I am using it works as a cellular and as radio Walky Talky, Nextel call this function as "Direct Connect" and in their Blackberry Contacts file they have a field for Direct Connect, so I created the equivalent field in my main PC ACT Database, but I see only a few fields at the Mobile live SYNC Settings and I would like to see more fields availables at the setting for synchronizing Contacts.
